The Confirmation Test – 2 Lens +/-0.25D is an essential tool for optometrists to refine and confirm eyeglass prescriptions, particularly for detecting minor refractive errors. This test involves using two lenses, one with a +0.25 diopter (D) and the other with a -0.25 diopter (D), to verify the accuracy of the initial prescription
These lenses are supplied in a sturdy box with foam inserts, ensuring they are well-protected and easy to store. The metal handle attached to each lens provides a comfortable grip, allowing optometrists to switch between lenses effortlessly during the examination
The primary purpose of the Confirmation Test – 2 Lens +/-0.25D is to fine-tune the patient’s prescription by confirming the detected refractive error. During the test, the optometrist alternates between the +0.25D and -0.25D lenses while the patient views an eye chart. This process helps determine whether the initial prescription needs adjustment, ensuring the patient receives the most accurate correction for their vision
Using this test is particularly beneficial for patients with borderline prescriptions, where small adjustments can significantly impact their visual clarity and comfort. It is also useful for patients experiencing symptoms such as eye strain or headaches, which may be due to minor inaccuracies in their current prescription
